Thanks Pete. I read your post on managing weight and humidity, and have weighed my eggs, and calculated expected weight loss. I really like the idea that I can kind of see how things are going and if they're on schedule. I'll save this one too. This is my first hatch, so I'm excited and apprehensive at the same time.

So, they sat for 24 hours, then went into the incubator at 100 deg. at 5 pm today. The detached air sac eggs are positioned vertically in egg carton cups and the others are laying horizontally in the lids. The humidity is a little high, but the plug is out, so hope it will lower pretty quickly. I turned the horizontal eggs after 4 hours, the only turn they got today as I went to bed after that. I left the vertical ones alone, per pete55's damaged air sac instructions (great instructions by the way; easy even for 1st timers to understand).

some of mine that i ordered through mail were 10-11 days old due to the post office messing things up. everyone thought i should just toss them but at day 5, 13 look good, one looks like a blood ring, and 4 appear to be duds (i also have 3 of my marans eggs that i cant see a thing in them). i have about 6 (as i havent counted to see how many) that are the 10-11 day olds. i havent tossed any and wont till at least day 10 which will be friday. i must say i am glad i didnt toss any of the eggs. wish i could get pics but my cam doesnt seem to take good pics of candled eggs.

So, I got 8 more eggs in the mail today. Denver is having a cold spell and my incubator is having a hard time keeping up. I knew the house wasn't a good temp for keeping the new eggs for the 24 hours (too cold without heat, too hot with) and since none appeared to have detached air sacs or been traumatized (yeah, I know you can't always tell), I stuck them in the incubator too. They should be hatching about 3 days apart.

I recandled a couple of the eggs with detached sacs and it looks like 1 had reattached and the other was better, but not totally stable yet. I'm not going to candle them again until after the 48 hours of no turning (and when it's warmer so they and the incubator doesn't cool off too much). Then, I figure I'll candle them all again and see how they're doing.

I am assuming that the colder temp is going to slow down hatching a little bit, but hopefully not damage them so badly they don't hatch at all. The incubator is running the heater all the time and my thermometers say between 96 and 98. I can't get it higher. On the other days, it's been 99-100. Keeping the humidity stable has been hard too as it snowed all day today and that changed the humidity of the air impacting the humidity inside the bator.

I'm stlll hoping, though. This season is a little ambitious for a first timer, I think, then I have to add the complications.

Burr for you in the Denver area!
When I do winter hatches in my poorly insulated house, I will wrap the incubator with a blanket, being very careful to not cover the heater (fire issues) or the vents (Oxygen issues). It seems to help.

Yes, thank you. I'm sure it will get cold again and I will think to do this. My husband is convinced at least half will hatch because "where are we going to put all these chickens when we add those too."
